No, you cannot directly insert an ISO30 tool holder into a BT30 spindle. The two types of tool holders have different tapers and dimensions, and are not compatible with each other.
ISO30 and BT30 are both common types of tool holder tapers used in CNC machining centers. The ISO30 taper is a 30mm taper with a 12-degree angle, while the BT30 taper is a 30mm taper with a 30-degree angle. While both tapers are designed to hold tools securely in a spindle, they are not interchangeable due to their differences in taper angle, length, and other dimensions.
If you need to use an ISO30 tool holder in a BT30 spindle, you would need to use an adapter. However, it’s important to note that using an adapter can affect the rigidity and accuracy of the tool setup, and may not be suitable for all applications. It’s recommended to consult with the machine tool manufacturer or a qualified tooling supplier before using an adapter.
